HIGH-PRESSURE REDUCING AND NOISELESS VALVE FOR FLUSH-TANKS.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed Harchfi, 1909. Serial No. 481,737.

To all whom it may concern:

Be it known that I, ALPHEUs G. VIRKLER, a citizen of the United States, residing at Lowville, in the county of Lewis and State of New York, have invented certain new and useful Improvements in High-Pressure Reducing and N oiseless Valves for Flush- Tanks; and I do hereby declare the following to be a full, clear, and exact description of the "invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon,which form a part of this s ecification.

This invention re ates to new and useful im rovements in high pressure reducing va ves and the object in view is to produce asimple and efiicient apparatus of this nature which will be noiseless in operation and dispensing with springs commonly employed for seating valves. 7

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the ap ended claims.

y invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view through the valve, and Fig. 2 is a side elevation.

Reference now being had to the details of the drawings by letter, A designates a tube or i e having its u per end recessed at A an( orming a seat or the valve member B which is fixed to the stem B.

C designates a valve member casing having a transverse partition which is apcrtured for the reception of the stem B of said valve member and is also chambered to receive a hollow plug E through which the stem passes. Said stem has a piston member, designated by letter F, of ar er diameter than the valve member B an is held between the disks F upon said valve stem. The pipe or tube A, which has threaded ends, has threaded connections with one end of said shell and is adapted to pass through the bottom H of a flush tank or other receptacle in which the ap aratus is adapted to be positioned. Suita le washers I are interposed between the shell and the upper surface of the bottom H and also between the nut J and the under surface of said bottom H, and to the lower end of the pipe is adapted to be the upper movement of the latter and an a erture L leads from said chamber L t rough the wall N of the shell into a branching duct or passageway N which leads from the chamber P below the partition C. A flow actuated valve, designated by letter R, is mounted in a chamber R of said branching duct or passageway andis adapted to seat against a shoulder R formed in the circumferential wall thereof. The valve R is provided with a stem R assing throu h a threaded cap R which is fi tted to threads in the upper end of the passageway R. Leading from the chamber R is a port or passageway S, and S designates an outflow pi e from which leads the usual refilling tube Pivotally mounted upon the fin ers S of the shell is a lever S the free end 0 which is adapted to bear against the stem R to hold the valve R seated, while its other end is provided with a threaded aperture for the reception of the tightening screw S which also passes through the forked end of the socket member 5*", the inner faces of the forked end of the member S having serrations about the apertures therein adapted-to intermesh with one another, said screw being adapted to pass through apertures in the ends of the member S and, when tightened, to cause the member S to be held in different adjusted positions. The socket member-S has a stem S of a float, not shown, connected thereto and which float is designed to rise and lower with the water in a tank.

In operation, when the flush tank is full, the stem of the float and the various parts of the apparatus will assume the osition shown in Fig. 1 of the drawings. en the tank is flushed by the opening of the valve to allow the water to make exit therefrom and which exit valve is not shown in the drawings, the stem of the float will lower and the pressure of the water main connected to the pipe A will overbalance the valve member B and valve R and allow the water to flow up through the pipe A, the shell and branching assageway N therein and make exit throng the outflow pipe S in the tank. As the float rises with the water in the tank, the valve R will be gradually closed and the pressure of the inrushing water through the pipe A and passageway -.N'* will cause the chamber L to fill with the same pressure and which, acting upon the piston member F which is of larger area than the valve member B, will cause the latter to seat and shut ofi the supply of Water. The refillin tube S affords means whereby water may e fed from the apparatus to the pipe S in the usual way.

By the provision of the apparatus as shown and described, all springs are dispensed with and a practically noiseless high pressure reducing valve is afforded and which is automatic in its action.

What I claim as new is 1. A high pressure reducing valve comprising a valve casing having a plurality of chambers therein, a valve stem movable through an aperture in the wall separating said chambers, members of different diameters fixed to said stem and one positioned in each of the chambers thereof, a tube 'connected to said casing and against which the smaller of said members is adapted to seat, a passageway leading from one of said chambers and communicating with the other above the larger member, and a float actuated valve positioned in said passageway, as set forth.

2. A high pressure reducing valve comprising a valve casing having a plurality of chambers therein, a valve stem movable through an aperture in the wall separating said chambers, members of different diameters fixed to said stem and one positioned in each of the chambers thereof, a. tube connected to said casing and against which the smaller of said members is adapted to seat, a

passageway leading from one of said chamers and communicating with the other above the larger member, saidpassageway having a shoulder formed in the wall thereof, a valve adapted to seat against said shoulder, and a floatadapted to regulate the valve in said passageway, as set forth.

3. A. high pressure reducing valve comprising a valve casing having a plurality of chambers therein, a valve stem movable throu h an aperture in the wall separating said 0 ambers, members of different diameters fixed to said stem and one positioned in each of the chambers thereof, a tube connected to said casing and a ainst which the smaller of said members isai lapted to seat, a cap fitted to the upper ;end of said casing and haying a recess therein adapted to receive and guide said stem, said casing having a laterally extending passageway communicating with the chamber in whlch the larger of said members is held, and a float actuated valve mounted in'said passageway, as set forth.

4. A high pressure reducing valve comprising a valve casing having a'plurality of chambers therein, a valve stem movable throu h an aperture in the wall separating said c ambers, members of diflerent diameters fixed to said stem and one positioned in each of the chambers thereof, a tube connected to said casing and against which the smaller of said members is adapted to seat, a cap fitted to the up er end of said casing and having a recess t erein adapted to receive and guide said stem, said casing having a laterally extending passageway communicating with the chamber in which the larger of said members is held, the circumference of said passageway having a shoulder forming a valve seat, a threaded cap fitted to the upper end of said passageway above said shoulder, a valve and stem positioned in said passageway, a pivotal lever bearing against thestem of the valve in said passageway, a float stem connected to said lever, an outflow pipe leading from said passageway above the valve therein,'and a refilling tube leading from said outflow pipe, as set forth.

5. A high pressure reducing valve, comprising a valve casing having a plurality of chambers therein, a valve stem movable throu h an aperture in the wall separating said chambers, members of different diameters fixed to said stem and one positioned in each of the chambers thereof, a seat for the smaller of said members, a passageway leading from one of said members and communicating with the other above the larger of said members, and a float-actuated valve positioned in said passa eway, as set forth.

In testimony whereof l hereunto affix my signature in the presence of two witnesses.
